I have my disc partitioned 100 gig for Op systems and programmes (C:), and the balance for data (F:), all in a master folder called "My Documents" with sub and sub sub folders such as "Word Docs", "Music" , "Photos" etc. I have a number of other drives. For the C drive I use Acronis to do an image, verified(to another drive), every couple of weeks after an anti virus and anti malware scan and a defrag. I use Freefileshnch every day to make a "mirror image" of the data partition (Far quicker than Acronis) . About once a month I make an Acronis clone of the whole main drive to yat another HD. Acronis seems to be well praised on this forum.
